Safe sex on period now I'm having pain in my lower abdomen and that the third time I had sex what wrong with me and the pain didn't come till the next day and also hurts to pee

First of all, there is no such thing as safe sex. The only safe sex is no sex.

Secondly, please see a doctor about this pain. We can't diagnose over the Internet.

We don't know! See your doctor.
